The function iplFixedFilter() is used to convolve the input image
srcImage with a predefined filter kernel specified by filter .The
resulting output image is
dstImage .
The
filter kernel can be one of the following:
IPL_PREWITT_3x3_V A gradient filter (vertical Prewitt operator).
This filter uses the kernel
-101
-101
-101
IPL_PREWITT_3x3_H
A gradient filter (horizontal Prewitt operator).
This filter uses the kernel
111
000
-1 -1 -1
IPL_SOBEL_3x3_V A gradient filter (vertical Sobel operator).
This filter uses the kernel
-101
-202
